Internally-threaded oil lubrication rod end joint bearing with larger swinging angle

更大摆角内螺纹油润滑杆端关节轴承

Abstract

The utility model relates to an internally-threaded oil lubrication rod end joint bearing with a larger swinging angle. The internally-threaded oil lubrication rod end joint bearing with the larger swinging angle is provided with an oil and grease dual-lubrication system, has the larger swinging angle, and is higher in impact resistance and long in service life. The joint bearing comprises a bearing rod end body and a bearing rod, wherein an inner circle and an outer circle of the joint bearing are arranged in the bearing rod end body. A structural key point is that the inner circle has an outer spherical surface; the outer circle has an inner spherical surface; the inner and outer circles are integrally assembled at a swinging angle of more than 15 degrees; an inner circle inner oil groove, an inner circle outer oil groove and an inner circle oil hole for connecting the inner circle inner oil groove with the inner circle outer oil groove are formed in the inner circle; an outer circle oil hole and an outer circle oil groove are formed in the outer circle; the inner circle oil hole is communicated with the outer circle oil hole; an oil nipple communicated with the working surfaces of the inner and outer circles is also formed in the bearing rod end body; a threaded hole is formed in the bearing rod.
